Loose connections
Action:
• Be sure all power cords are securely connected.
• Be sure all cables are properly aligned and securely connected for all external and internal
components.
• Remove and check all data and power cables for damage. Be sure no cables have bent pins or
damaged connectors.
• If a fixed cable tray is available for the server, be sure the cords and cables connected to the server
are routed correctly through the tray.
• Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
• If a device has latches, be sure they are completely closed and locked.
• Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
• If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.

Problem diagnosis
This section covers the steps to take in order to diagnose a problem quickly.
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page
26)," and follow the appropriate diagnostic path. If the other
flowcharts do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis
flowchart (on page 27)." The General diagnosis flowchart is a generic troubleshooting process to be used
when the problem is not server-specific or is not easily categorized into the other flowcharts.
